Problems solved by technology

[0003] At present, the edge localized mode control of magnetic confinement nuclear fusion plasma adopts the preset system trigger time, that is, it does not have the ELM real-time control function, so it is impossible to implement corresponding control according to the ELM type and state in real time, so the ELM control effect and success rate Both are poor and cannot reach the ideal state

Abstract

The invention belongs to the technical field of controllable nuclear fusion, and particularly relates to a magnetic confinement nuclear fusion plasma edge local model real-time control system and method. The system comprises: a vacuum docking system which is used for docking with a nuclear fusion device; an impurity injection system used for controlling injected impurities; and an ELM early warning system used for carrying out rapid real-time identification and early warning on the ELM category. The real-time performance and reliability of magnetic confinement nuclear fusion plasma edge local module control are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of controllable nuclear fusion, and in particular relates to a real-time control system and method for edge localized mode of magnetic confinement nuclear fusion plasma. Background technique [0002] Magnetically confined plasma high confinement mode (H mode) is a self-sustaining mode of operation of fusion reactors. The main feature of H mode is the formation of a steep pressure gradient at the plasma edge, which leads to the generation of plasma edge localized mode (ELM). During the ELM explosion, a large number of plasma particles and energy storage are lost from the plasma. These particles and energy are deposited on the first wall of the device to form an extremely strong thermal load. When the load limit of the wall material is exceeded, the wall material will be melted and corroded, or even damaged. , thus posing a fatal threat to the safe operation of the device. In addition, when the particles caus...
